STEP 1
CAD
Computer Aided Design (CAD) is software that allows for the construction of objects in a virtual environment. Examples include Auto desk, Solidworks and many others.

STEP 2
STL
The STL file format is the most widely used file format for 3D printers. It converts 3D models into a readable format for the printer. If your STL model is rough, so will be your printed object.

STEP 3
3D Printer Type
Setup depends on the printer type, where FDM is a plastic filament that is melted, SLA is resin based and SLS is powdered based.
